Abstract

A dynamic simulation model for binary distillation is presented. The
model is based on mass, component and energy balances as well as
pertinent expressions for the thermodynamic properties of the binary
mixture. The model includes a total condenser, producing a reflux with a
varying degree of subcooling, and a thermosyphon reboiler, which
introduces several operating parameters. Parameters related to the
operation of the condenser and the reboiler as well as tray efficiencies
and heat losses from the column are determined by fitting to
experimental data.
